IMPROVEMENT IN HOISTING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom 'it 'ma-y concern Beit known that I, Nroorlaus WosLARLAnsKY, of

St. Petersburg, in the Empire of Russia., have invented a new or Improved 'Apparatus for Raising, Lowering, and Transporting or Removing Goods and do hereby declare that thc following description, taken in connection with the accompanying drawing hereinafter referred to, forms a full and exact speeilication of the same, wherein I have set-forth the nature and principles of my said improvement, by which my invention may bc distinguished from others vof a'g similar class, together with such parts as I claim and desire to secure by Letters Patent, that is to say- This invent-ion has reference to a new or.i mprove'd ,portable apparatus of simple and inexpensive construction, principally intended for loadingl and unload- 'ing goods of moderate weight, suc'lrx` as "are generally 'moved by manual labor, the employment of cranes being usually' limited to goods of not less than ten hundred weight.

The said apparatus consists mainly of a beam snspended at any desired height'from'a tripod, upon which' beam is situated a small carriage, with lifting tackle for raising and conveying the goods, the beam'being steaded while in use by means. of guy-ropes or chains. The beam is by preference provided with three suspending hooks fixed at 'different points of its length, by either of which it is suspended either directly or with the intervention of lifting tackle from the tripod, and is held in amore or less inclined position by the before-mentioned guy-ropes or chains secured in any suitable manner to the'- ground.

The beam is inclined from the place where the goods I are to kbe-unloaded to the point Where they are to be deposited, so that, on the load being suspended from the carriage, this will, by virtue of the gravity of the load, of itself run down the inclined beaitI to the end, where the goods are to be unloaded, and thus the expenditure of power for 'removing the goods from the one point to the other will be obvi'ated,

The raising of the load at the first-named point, and

the lowering of the same at the last-named point, are effected by means of the before-mentioned liftingtackle, the hauling end of the rope or chain of which is allowed to slip through the hand of the operator while the load suspended from the carriage is passing with the same along the beam. After depositing the load the carriage is drawn back to the loading end of the beam bythe said hauling end of the lifting-tackle. The construction of the before-described portable apparatus for loading and unloading will he readily understood upon reference to the accompanying drawing, in which similar parts are indicated by similar letters of 'reference in each of the figures.

' Figure 7 shows an enlarged View of the suspending loop c.

Figure 8 shows a part enlarged section and elevation of one of the poles a..

Figure 9 shows an enlarged view of the connectingbolt l), which is bent to the required curvature, as shown in iig. 1.

Figure 10 shows a transverse section of a solid form of beam, with modified construction of the carriage 7:.

a n a is the tripod or support, composed' of three poles of wood or metal, either solid or tubular, connested together at the upper ends in such manner by means of a. bolt 11 passing through the same that thev poles may be freely moved nearer together or furtherA apart or even laid closely side by side for convenience of transport.

The bolt b also carries the loop cto which the beam d d is hung, either directly, as shown in the drawing, or with the intervention of a differential pulley by means of one of the three hooks ce e.

The beam cl is constructed either of wood or preferably of iron or steel, and is composed of two flat bars, as shown in figs. 1 to 4,`which are secured together at a certainv distance apart by means of bolts or rivetsfh and distance pieces f at the ends, and by means of the yoke g carrying the suspension hooks e.

Upon the upper edges of these bars runs the carriage k, iigs. 1,5, and 6, from the eye n of which is suspended the load m, by means of the lifting-tackle l with hauling-rope or chain s, p

The carriage may either have only two wheels p, as shown, or it may be provided with four wheels.

The bridge-pieces g must be :of such a height that the carriage can pass through them on its way from one end ofthe beam to the other.

The lifting-tackle l, for raising,`lowering, and suspending the load, is-hooked into the eye n, which is suspended loosely upon the axle o of the carriage.

By suspending the beam d ou one of the two side hooks c instead of themiddle one, it may be made to overhang alconsiderable space, such asmight be necessary for loadingand unloading a barge, and it may alsoin thatcase be used as a lever.

`As before stated, the beam l may also be. of one solid piece of wood or other suitable material, as shown in the section at iig. 10. In this case the yoke gis dispensed with, and the suspending hooks e are fixed directly in the middle of the beam.

The wheels p of the carriage 7c are in this case conneeted bythe stirrups a from wlneh the lifting-tackle is suspended. By this arrangement it will be' seen that the carriage k can, as in the previous arrangement, pass the. hooks e on its way along the beam.'

1t will be self-understood that the strength ot' the, beam and other parts will have to be made in due proportion to the load the apparatus is intended to carry, and their form may also be varied according to circumstances without departing `from the nature of my invention. p

It the apparatus requires to from one locality to another, the suspension ofthe beam l may be advantageously effected by means Lof the well-known v\Vesto11s diierential pulley,7 with endlesshauling chain which is interposed betwxeeuthc suspension hooks c and the loop c of the support, so as to enable the beam to be raised and lowered, such differential pulley being of lwell-known construction, and forming no part of my present invention, it is not shown in the drawing.

lhe mode. of' operation with the apparatus is as follows:

The guy-ropes or chains fr r are secured to a lixedv object in such a manner that they hold the beam in a position incliuing from the place where the goods are situated to the. point where they are to be deposited; as, for instance, with the onev end ovcrhangng a rail'- way wagon and the other end over the platform. '.lhe load .is then suspended to the lower hook of the litting-tackle, is raised by the hauling-rope s, after which, hyletting the said rope slide through his hand, the op` erator allows the carriage `with its load, by virtue of its own gravity, to run down the inclined beam to the end, where the load is to be deposited. Arrived at suoli point, the load is lowered by the tackle, and, after unhoolting the latter, the carriage with the tackleA is tlrawn back to the other end of' the beam, and the operation is repeated. In order to talte the drag produced by the weight of the load oit` the operators hands while the carriage is passing along t-he beam, the load may, when raised to the requisite height, be hooked' on to a short independent length of rope or chain suspended from the carriage or upper pulley of the tackle, from which it is unhooked when arrived at the other end of the beam. f

By placing several of' the before-described apparatus end to end, it will be evident that the loads may be transported considerable distances -by transbe frequently shifted niitting the load when arrived at the end of the beam otoneapparat-us .to theearriage on the contiguous end ot' the beam to the next apparatus.

The advantages to be derived from the use of the bein'e-described apparatus arel"irst, its simple and inexpensive construction.

lbeeond, the ease with which it may be transported from place to plac'e.

Third, the rapidity with which goods maybe loaded or unloaded by means thereof.

Fourth, the great saving of manual labor effected by its use.

. It is therefore anticipated that this apparatus will meet with considerable applications at railway sta-vv tions, docks, landing places, factories, and for agriculf tural purposes, dto., for loading, unloading, and trans?V portinT goods of medium weight.

Having thus described the nature ot my invention and in what manner the same is to be performed, I wish it to be understood that` I am aware of the existence of traveling cranes, consisting of a horizontal beam supported at each end by traveling uprights trained rigidly with the said beam, and having a carriage, which is moved along the beam byineans ot' chains passing over guide-pulleys down to winches on each sideot the supports, and I therefore in no way claim such au arrangement; but

' 1. The beam d, suspended from a tripod,'a, guyropes r, carriage 7a, and lifting-tackle ts, substantially as and l'or the purpose set forth.

2. The beam d, formed with two cheeks upon the bar a certain distance apart,` connected by the yoke g with suspension hooks e, through which the carriage 7c passes, substantially as set forth.

3. 1n eoi'nbh'latiou with solid beam suspended from a tripod of a carriage, the wheels of which are connected by a stirrup partly encompassing the beaur, substantially and t'orthe purpose set i'orth.

4.` The apparatus for lowering, hoisting, and transporting, substantially as herein shown and described.

In testimony whereof, I have signed my name to this speeication in the presence of two subscribing witnesses this twenty-ninth day of August, 1870.
